Study of chaotic oscillators having passive fractal two-terminal elements
Ledvina, Matej ; Kaller, Ondřej (referee) ; Petržela, Jiří (advisor)
Táto semestrálna práca sa zaoberá chaotickými obvodmi s fraktálnymi prvkami. V prvej časti sú prezentované fraktálne prvky, ich vlastnosti a spôsob syntézy. Tri takéto prvky sú navrhnuté, vyhotovené a merané. V druhej časti je krátky úvod do problematiky chaotických obvodov, a spôsobov ich syntézy. Následne sú prezentované dve metódy syntézy chaotických obvodov s názorným príkladom. Na koniec bol vybraný jeden chaotický system ktorý bol syntetizovaný do obvodu, odsimulovaný, zhotovený a experimentálne overený.

Design of a New Filter Structure Employing Devices of Fractal Order
Detko, Adam ; Kubánek, David (referee) ; Bečková, Zuzana (advisor)
This thesis deals with fractional order analogue filtration structures. The first part focuses on theory of analog frequency filters, including fractal order. In the next part, some of the active elements that can be used in frequency filters designing are mentioned. In the third part, known integer order filtration structure working in current mode is shown, which is modified to fractal in the next part. Modification to fractional order filter is realized by the RC structure Foster I, which approximates fractal order element, also known as pseudocapacitor. This part also contains calculations. Next part contains simulation results, that have been made with ideal models of active elements. The fifth part deals with the design of original filtration structure and its subsequent modification to fractal order filtration structure. Last part contains results of simulations and their comparison with the theory and for low pass as well comparison with physically measured values.
